On Monday, I had a bit of time to kill in Rome between arriving from the USA and catching the bus to Amandola. At lunchtime, I was very happy to discover Forno Moderno in Via Marsala, just outside one of the side entrances to Stazione Termini. Forno Moderno is an island of genuine food in an area dominated by fast food bars and tourist restaurants. For the visitor who is passing through Termini and wants a good, healthy sandwich and not one with filled with "plastic" and artifical aromas, they offer a true, Italian alternative to McDonalds. Fresh bread (a huge variety including wholemeal and sesame seeds), prosciutto, salami, mortadella, good quality cheeses, grilled zucchini and eggplant, tomatoes, dried capsicum, lettuce - you choose your filling. It's also very reasonably priced. I paid €2.50 for a long bread roll filled with prosciutto and grilled eggplant.
Forno Moderno, Via Marsala 62, Roma.
